Metal–organic frameworks for upgrading biogas via CO2 adsorption to biogas green energy

Abstract

In the midst of the global climate change phenomenon, mainly caused by fossil fuel burning to provide energy for our daily life and discharge of CO2 into the atmosphere, biogas is one of the important renewable energy sources that can be upgraded and applied as a fuel source for energy in daily life. The advantages of the production of hybrid materials, metal-organic framework (MOF) adsorbents, expected for the biogas upgrading, rely on the bulk separation of CO2 under near-ambient conditions. This review highlights the challenges for MOF adsorbents, which have the greatest upgrading abilities for biogas via selective passage of methane. The key factors improving the ideal MOF materials for these high CO2 capture and selectivity uses for biogas upgrading to produce bio-methane and reduce fossil-fuel CO2 emission will be discussed.

Insights into CO2 and CH4 Adsorption by Pristine and Aromatic Amine-Modified Periodic Mesoporous Phenylene-Silicas

“…The powder was 8 filtered off, washed with ethanol and water and dried overnight at 60 °C. The confirmation of the template removal was made through 13 C NMR spectroscopy and TGA analysis. …”

“…13 The latter is a very attractive technique from small to medium-scale operations, but relies on the availability of highly effective adsorbent materials.…”

“…5,16,17 The LBSs in MOFs may also induce dispersion and electrostatic forces to enhance the CO 2 adsorption selectivity. 17,18 binding sites and provide strong affinity for CO 2 molecules. 19,22 The addition of amine functionalities to the linkers of IRMOF-1 to produce IRMOF-3 provides 0.4 wt% improvement in CO 2 uptake at 25°C and 1.1 bar, even though a decrease in the BET surface area of IRMOF-3 from 2833 to 2160 m 2 g −1 occurred.…”

Metal-Organic Framework as Catalyst in Esterification of Oleic Acid for Biodiesel Production

“…High porosity materials like metal-organic frameworks (MOFs) which constructed framework from inorganic (metals cluster/nodes) with organic (ligand/linker) offer tremendous possibilities for catalyst application since their properties in high porosity, surface area, and enable for tailor design for tuning the acidity/basicity properties [17][18][19]. Here, we proposed to use MOFs which their high stability in chemical, physical and thermal properties in reaction condition to investigate on esterification.…”

“…Some of the examples are ion-exchange resins having sulfonic acid groups [6], sulfated or mixed oxides [7], have been reported such as leaching of species in recyclability [15], high condition in term of temperature and reaction time on, the low diffusion of oil due to the small pore size, swelling tendency in solvent, low active site involve of low surface area etc [16]. On the basis of these considerations, the catalyst improvement of the esterification could represent one of the key points through which the whole process can result in being economically convenient.High porosity materials like metal-organic frameworks (MOFs) which constructed framework from inorganic (metals cluster/nodes) with organic (ligand/linker) offer tremendous possibilities for catalyst application since their properties in high porosity, surface area, and enable for tailor design for tuning the acidity/basicity properties [17][18][19].
